C1 Oil Gauge problem

[Mark Malone]

Hi Guys,

A buddies oil gauge in his 62 is reading full pressure (all the way to the right) when running but returns to zero when switched off.

I haven't done any work on a C-1 oil gauge so I'm not sure where to start.

Any help will be much appreciated.

Thanks, Mark.

Re: C1 Oil Gauge problem

Not sure there is anything wrong--if high volume/high pressure pump is installed on the engine, it could very well peg the gauge except after a long drive when oil is hot and thinned--at idle it might come down. My experience is that the gauge is not the problem--it's simply reflecting something going on in the motor.

Mark,
I have the high pressure oil pump and it does exactly that. After it gets hot it goes to about 50lbs on low RPMs.

My 55 has run

like that since I was a small child, both the original engine and the all-correct 55 replacement, 40-50 at idle, pegged out when driving.

{pegged out when driving} = Your going to blow a valve cover some day!!

Roy,

Why are you expecting this result because of high oil pressure. I would expect all part just be better lubricated?

I'm always eager to learn something each day...

greetings,
Rob.

Well, in fifty years and 122,000 miles

it hasn't yet, probably because I have the correct road draft tube installed, insuring no positive pressure can exist in the valve covers or anywhere else.

[Dave Suesz]

Theoretically yes, but very high pressure

can also indicate blocked oil passages, which means something isn't getting oil at all.

Rob! it was a joke!!!!!!!!!! You cant blow a valve cover off HA!
